[Hydrochloric acid, gastrin, parietal cell mass in active and quiescent phases of duodenal ulcers].

The A. studied the behaviour of gastric acid secretion, of gastrinemia and of the parietal cell mass in 14 patients with duodenal ulcer (in active state and then in quiescent state) and in 20 symptom free control subjects, in absence of circumscribed gastroduodenal lesions. The analysis of the results demonstrates the persistence in the quiescent state of the physiopathological behaviour found in the active duodenal ulcer.
